Are there any freely available decoders than can decode AAC-ELD encoded from fdkaac.exe?
Do you really need it?
QuoteDo you really need it?Nope I just wanted to test out AAC-ELD against Opus
I ran [a href='index.php?act=findpost&pid=716229']these samples[/a] by Case, with various encoding modes, and although I don't necessarily hear a gap, he claims to hear a loud pop on track change transition.

It can be used as such:Bitrate ModeCode: [Select]avconv -i <input> -c:a libfdk_aac -b:a <bitrate> -afterburner 1 <output>VBR ModeCode: [Select]aconv -i <input> -c:a libfdk_aac -flags +qscale -global_quality [1-5] -afterburner 1 <output>VBR modes 1-5 correspond to roughly:about 32 kbps/channelabout 40 kbps/channelabout 48-56 kbps/channelabout 64 kbps/channelabout 80-96 kbps/channel-afterburner 1 enabkes "improved quality" mode.

aconv -i <input> -c:a libfdk_aac -flags +qscale -global_quality [1-5] -afterburner 1 <output>
... with a lowpass filter of 18500.
Quote from: sluggy on 22 March, 2013, 09:41:08 AM... with a lowpass filter of 18500.How do you do this? libfdk_aac (ffmpeg) or fdkaac don't have any option to configure the lowpass filter and the vbr modes are predefined.If you're using the Winamp version then configuring the lowpass in Winamp will be a waste of time (or worse) because the encoder will still apply its own lowpass filter regardless, see http://www.hydrogenaudio.org/forums/index....st&p=824223I suspect that if you make a spectrogram of any of your files made with "vbr 4 with a lowpass filter of 18500" it will show a hard cut off at about 16k.edit: -vbr 5 with custom lowpass might be possible.
nu774, your news page has the changelog for fdkaac 0.2.0, where can I find the one for 0.3.0?
- Enhanced Low Delay AAC (ER AAC ELD) decoding (no LD SBR support)
I can't get the .exe with fdkaac_autobuild.zip, trying to get 0.4.2. 0.4.1 worked.
